Method and apparatus for secure setup of clinical trial client device

ABSTRACT

A method, device and system for transceiving clinical trial related information includes a client device and a server that communicate. An application of the client device has a client application of a clinical trial service whose server application is running on the server. A coordinator user profile with credentials and a user profile with credentials are maintained. The coordinator credentials are determined to be be authorized. The coordinator user obtains access to the application. Coordinator input data triggers user change for the client device. A request to the server application indicating the triggered user change is sent. Credentials are received from the server application and associated with the user profile. The coordinator user is logged out by disconnecting coordinator level access to the proprietary application and resetting the coordinator credentials and session data within the client device. The credentials are stored for automatic first logging in of the user.

TECHNICAL FIELD

The present application generally relates to clinical trials and securely setting up client devices for subject users of the clinical trial.

BACKGROUND

This section illustrates useful background information without admission of any technique described herein representative of the state of the art.

New medical innovations, such as new drugs, medical devices, or medical applications, are often researched and tested using clinical trials. Trials require more than one phase of testing that take several years and cost considerable amounts of money to perform.

Clinical trials are typically classified into 4 phases (unless trial is interrupted or closed). Clinical trials of drugs may not fit into a single phase. For example, some clinical trials may blend from phase I to phase II or from phase II to phase III. The drug-development process may normally proceed through all four phases over many years. If a drug successfully passes through phases I, II and III, the drug may be approved by a national regulatory authority for use in general population, for example. Phase IV may correspond to ‘post-approval’ studies.

Each phase has a different purpose and helps researchers answer different questions. In phase I trials, researchers test an experimental drug or treatment in a small group of people (20-80) for the first time. The purpose is to evaluate its safety and identify side effects. In phase II trials, the experimental drug or treatment is administered to a larger group of people (100-300) to test its efficacy or effectiveness and to further evaluate its safety. In phase III trials, the experimental drug or treatment is administered to larger groups of people (1,000-3,000) to confirm its effectiveness, monitor side effects, compare it with standard or equivalent treatments, and collect information that will allow the experimental drug or treatment to be used safely. In phase IV trials, after a drug is approved by a regulatory authority, such as Food and Drug Administration (FDA) in the USA, and made available to the public, researchers track its safety, seeking more information about a drug or treatment's risks, benefits, and optimal use.

Typically, a clinical trial or study is funded by a sponsor, such as a private company, medical or research institution, federal agency, or by an entity established by a collaboration of such groups. The sponsor may employ one or more clinical investigators or research assistants to oversee administration of and/or monitor the study at one or more investigation sites. Each investigation site may include a number of study participants.

When a participant in a clinical trial fills in an electronic diary or study, a client device is used. The device may be used by a plurality of subject users one after another, clinical trial after another.

Traditionally, when a site coordinator sets up the client device to be handed over to the subject user, username and password are delivered to the subject user by email or simply typed or printed on paper. The client device with an application being used for processing and/or transceiving data relating to a clinical trial is set up and provisioned by site personnel and handed over to a subject user. Resetting currently authenticated user session before authentication of the next subject user may needed to be done manually by the site personnel.

Thus, a solution is needed to enable more secure and efficient resetting of earlier session data and providing credentials for the subject user when providing a client device to be used in a clinical trial.

An electronic diary is a tool used during a clinical trial to register assessment of a participant's condition (e.g. symptom severity, quality of life) by the participant. The electronic diary registers data in a storage device and allows for automatically monitoring the time the entry was made. Frequent recording of symptoms using a diary helps to reduce recall bias. Electronic diaries enable entries are made as scheduled, and not, for example, in a batch immediately before the clinic visit. Electronic diaries also enable finding out if a participant takes the medication according to the treatment schedule, which is important during clinical trials. Investigators, on the other hand, are assessing the received data that was registered by the electronic diary.

In an embodiment, information relative to a clinical trial between a client device 120 operable by a plurality of users and a server apparatus 130 is transceived. The client device 120 and the server apparatus 130 are configured to communicate via a data network 150. A proprietary application 124 of the client device 120 is a client application of a clinical trial service whose server application 133 is running on the server apparatus 130, wherein a coordinator user profile associated with coordinator credentials and a subject user profile associated with subject credentials are maintained by the server application 133 at the server apparatus 130. The proprietary application 124 may comprise, for example, the electronic diary tool or any kind of client application as disclosed in different embodiments, such as an electronic consenting application, for example.

The coordinator credentials may be received via a user interface by the proprietary application 124, 164, and the coordinator credentials accepted in response to determining the coordinator credentials being authorized credentials, and logging in the coordinator user by providing coordinator level access to the proprietary application 124, 164.

Furthermore, coordinator input data may be received by the proprietary application 124, 164 configured to trigger user change for the client device 120. A request may be generated and sent by the proprietary application 124, 164 in response to the coordinator input data, to the server application 133 indicating the triggered user change.

In an embodiment, coordinator input data may be received by the proprietary application 124 configured to trigger user change within the client device 120. A request may then be automatically generated and sent by the proprietary application 124 to the server application 133 indicating the triggered user change. In response to the request, subject credentials may be received by the client device 120, for example.

In an embodiment, coordinator input data may comprise any input data indicating user change for the client device, setup for the client device, setup for the proprietary application or merely exit function (trigger “exit” via user interface) by the coordinator to close the coordinator session and initiate subject user login, for example.

Then again, subject credentials may be received by the proprietary application 124 from the server application 133, wherein the subject credentials are associated with the subject user profile generated by the server application 133. The coordinator user may be logged out by disconnecting coordinator level access to the proprietary application 124 and resetting the coordinator credentials and session data within the client device 120, and the subject credentials may be stored by the proprietary application 124 for automatic first logging in of the subject user.

In an embodiment, the request may be sent, in response to the coordinator input data, by the proprietary application 124 to the server application 133 indicating the triggered user change and comprising an identifier for the subject user.

An electronic diary may comprise a computer-implemented client software application for a participant of a clinical trial to record data for the clinical trial. The electronic diary may also comprise a computer-implemented web browser application. The electronic diary may also comprise a combination of a client software application and a browser application.

The electronic diary allows only registered participant to record data. Typically, the electronic diary may remind the participant to fill in data at scheduled time according to a trial protocol and may present only questions the participant should answer at that time, for example. In addition, the electronic diary may time stamp the recorded data and maintain an audit trail of changes to the data in order to ensure the integrity and validity of the clinical trial related data.

The use of electronic diaries is regulated by laws and guidelines from local authorities as well as GCP (Good Clinical Practice). These regulations typically require that clinical trial participants are authenticated prior to entering the proprietary application 124, such as electronic diary, to ensure that participant privacy is not compromised and to ensure that the data is recorded by the participant and not by someone else. Secure subject user credentials may be generated and allocated by the server application 133 running at the server apparatus 130.

In an embodiment, the proprietary application 124 may require login identification information to participants allowed to use the proprietary application 124. The identification information may comprise credentials, such as a participant login name and an associated password. The term “participant” refers to a person (such as e.g. a subject user, a guardian of the subject user, a care giver of the subject user, or an observer of the subject user or an animal, for example) using the proprietary application 124, such as an electronic diary, to record and submit participant-reported data (such as participant diary data or other related clinical data, or a person (e.g. a subject user) receiving information regarding a clinical trial during an electronic informed consent session, for example) for use in clinical trials run by pharmaceutical industry, for example. Typically, the participant needs to be registered before allowed in the clinical trial. The participant may utilize an electronic diary 124 within a client device 120 (such as a smart phone, a personal digital assistant, a tablet or a laptop computer, for example) to record and send participant data.

In an embodiment, registration of a subject user for the clinical trial may take place before consenting of the subject user, or together with the consenting session. Registration and/or consenting can also take place when the clinical trial starts, for example when the subject user gets the client device to be used for the clinical trial and/or consenting. Registration and/or consenting may be carried out using a proprietary application comprising a client application, a client plugin or a client web session, for example.

In an embodiment, a client device 120 may be used by a plurality of participants. In such case the client device 120 may generate event entries or other clinical trial related data by different users to be transmitted to the server 130, 131 using the same client device identifier. When handing the client device 120 from first user (e.g. coordinator) to second user (e.g. subject user), the first user's session data needs to be reset and credentials for the second user easily and securely provided.

Participant data and an identifier of the participant are received at a participant data collector server 130, 131 by the server application 133. The participant data is entered by the participant using the client device 120 or a personal device 110 without user input. Thus, the participant data is recorded by the proprietary application 124 that sends the participant data to the server application 133. The personal device 110, such as a wearable device, may independently send data to the server 130, 131 or to the proprietary application 124, to be appended to the participant data. In case the personal device 110 sends independently the data to the server 130, 131, the personal device may transmit an event log corresponding to event entries of an electronic diary of a participant of a clinical trial, wherein the event log is generated in the personal device, and the event log comprising an event identifier and an event timestamp for at least one event entry that can be associated to participant data for investigation at the server 130, 131 based on a device identifier or participant identifier, for example.

A typical clinical trial begins with the construction of a clinical protocol that describes how a trial is to be performed, what data elements are to be collected, and what medical conditions need to be reported immediately to the pharmaceutical sponsor and the regulatory authority, such as Food and Drug Administration (FDA) in the USA, for example. The clinical protocol and its author are the ultimate authority on the conduct of the clinical trial. This protocol is the basis for every action performed by multiple players in diverse locations during the entire conduct of the trial. Any deviations from the protocol specifications, no matter how well intentioned, threaten the viability of the data and its usefulness for the regulatory authority, such as Food and Drug Administration (FDA) submission in the USA, for example.

Participant compliance is important for a clinical trial. Participant may be required to take medication and follow the regimen at times specified by the protocol. Additionally, an electronic diary is filled to provide participant data at times specified by the protocol. For instance, the protocol may specify that the participant needs to take certain drug at certain times. The protocol may define, for example, that certain drug should be taken on Day1 and report symptoms on Day2 and again on Day3, Day4, Day5, etc., each entry with their own date/timestamp.

Consent to participate in a clinical trial should be obtained. A list of registered users may be provided with consent information. Furthermore, for whom consent was obtained can be outputted and forwarded to an entity involved in the clinical trial. Typically, this is a drug company.

Because participant confidentiality is important, anonymity of a person meeting the specified criteria must be preserved. The process of obtaining consent may include meeting specified criteria for approval to participate in the clinical trial.

In an embodiment, the method can first include the steps of obtaining consent or authorization of the prospective participant, obtaining identifying information from the prospective participant, and generating personal identifying information, for example. The personal identifying information can comprise biometric data and information.

Secure setting up a client device 120 for clinical trial related information, such as consenting, re-consenting or the clinical trial subject user data, has certain problems or drawbacks. Method for providing credentials, such as a username and a password may not be universally convenient or successful for every participant as there could be number of complications. One may not have an email account, a printer may not be available or it simply can lack paper or ink etc. Again, the password generated may be long, complex and characters may be difficult to distinguish from each other (I, I, 1; O, 0; vvvv, ww, for example), thus making the input of the credentials tedious and cumbersome. Also, the client device 120 in use, especially if a touch device in question may be a new experience (as a device type) to a subject user, making the data input event of username and password even further difficult to execute.

Re-consenting may be needed, for example, if the clinical trial protocol or the original consent is invalid or there has been a substantial change to the research or trial protocol or to the subject user's condition since the time of the original consent, such that research participation may no longer be consistent with the subject's preferences and interests and the subject may need to reconsider the decision.

Typically, clinical trial including needed consenting steps may last for years. Thus, the client device used by the subject user may become obsolete, break down, or have some malfunctions during that time. It may be that the client device cannot be repaired, for example due to lack of spare parts, such as batteries. In such case, for example, the embodiments disclosed enable setting up the replacement client device.

Furthermore, a subject user in device handover situation may find using the device difficult due physical attributes of the user. For example, fingers may be too large compared to active areas on screen, keyboard keys are too small for a finger, coordination of movement of fingers is difficult due to a disease (e.g. Parkinson's disease) or similar condition.

Further problems may relate to password/username, such as an unfamiliar or strange character may be difficult to locate in a keyboard or it may be difficult for the subject user to see and understand different user interfaces and states of the user interface, e.g. when a key is pressed the key changes from inactive to active state. Other usability challenges may exist relating to virtual keyboard, Caps Lock, and disturbing notifications presented to the user, for example.

Only exemplary problems are mentioned to illustrate the challenges for the subject user to fill in secure user credentials for the proprietary application 124 to transceive clinical trial related data(pre-trial, on-trial or post-trial).

The problem is evident and disturbing mostly in user experience perception of the service, hence rendering the overall service difficult or slow to use. Limiting the problem as much as possible would allow clear benefit for service provider and subject user as more efficient, easier to use and faster clinical trial data transceiving between the proprietary application 124 and the service application 133.

The wireless interface may comprise such as a WLAN, Bluetooth, infrared (IR), radio frequency identification (RF ID), NFC, GSM/GPRS, CDMA, WCDMA, LTE (Long Term Evolution) or 5G radio module. As the radio technologies are evolving and new replacing systems being developed, the new developed technologies can be used for the communication interface module 350 in view of different embodiments disclosed. The communication interface module 350 may also comprise non-RF connection, such as Light Fidelity (Li-Fi). The wired interface may comprise such as universal serial bus (USB), for example. The communication interface module 350 may be integrated into the device 120, or into an adapter, card or the like that may be inserted into a suitable slot or port of the device 120.

A skilled person appreciates that in addition to the elements shown in FIG. 3, the device 120 may comprise other elements, such as microphones, speakers, sensors, cameras, as well as additional circuitry such as input/output (I/O) circuitry, memory chips, application-specific integrated circuits (ASIC), processing circuitry for specific purposes such as source coding/decoding circuitry, channel coding/decoding circuitry, ciphering/deciphering circuitry, and the like. Additionally, the client device 120 may comprise a disposable or rechargeable battery (not shown) for powering when external power if external power supply is not available.

In an embodiment, the client device 120 comprises speech or gesture recognition means. Using these means, a pre-defined phrase or a gesture may be recognized from the speech or the gesture and translated into control information for the device 120.

In an embodiment, the disclosed solution automatically takes care of manual login procedure on behalf of the subject user.

A site coordinator may log in, and create or pick readymade account credentials (username and password) for the subject user via the proprietary application 124. The selected credentials are received from the server application 133. The coordinator may then log off manually or is logged off automatically. The created subject user credentials are not cleared from the client device memory 320 but are saved for optionally recovery purposes and especially for the login step of the subject user. The login step can automatically use the received subject user credentials for logging in and authentication on behalf of the subject user.

In case of auditing or due to other reasons, if for example regulations prevent or discourage automatic logging in, the subject user may be provided with a “log in” function or touch sensitive key on the user interface 340 to be triggered in order to record, indicate or control the exact time when the subject interaction started. Another reason for leaving the “log in” function triggering to the subject user may be the use of digital signing, e.g. by fingerprint sensor 360, 370, prior to or during logging in, wherein the signing by subject user's fingerprint may be used in later phases of the clinical trial process.

Alternatively, if the client device 120 is known to be used only in controlled or on restricted areas, premises, situation or network, then default or automated set-up procedure could be applied. Here, an active coordinator contribution is not necessarily required otherwise but only to put the client device 120 available for the subject user to pick it up for the clinical trial. The client device 120 could allow, by the proprietary application 124, simple automatic or manual function of “create new user” or “pick from list” relating to the subject user. In simplest form, the subject user can make or initiate the setup simply by taking the client device 120 into use. Taking the client device 120 into use could be based on event such as: movement of the client device 120 (e.g. pitch, yaw, roll, moving in x-y-z coordinate space), powering-up, launching an application (e.g. proprietary application 124), activating an application (e.g. proprietary application 124), manipulating application (e.g. proprietary application 124) or client device 120 control items such as button, enablement of client device 120 network connection or physical positioning (coordinates). After the set-up action, the client device 120 with an application (e.g. proprietary application 124) could provision the subject user automatically as an authenticated user for the clinical trial.

FIG. 4 shows a flow chart of operations according to an example embodiment of the invention.

First in step 410, coordinator credentials are received via a user interface 340 of the client device 120 by the proprietary application 124, and the coordinator credentials are accepted in response to determining the coordinator credentials being authorized credentials, and logging in the coordinator user by providing coordinator level access to the proprietary application 124.

Second in step 420, the coordinator is logged in for using the proprietary application 124 with coordinator access rights and may trigger administrative tasks and processes relating to subject users and the clinical trial data.

Third in step 430, a subject user may be determined and subject user's username and password may be fetched from the server application 133 (backend system) while the coordinator user is logged in and working on the client device 120.

Fourth in step 440, the coordinator user activates the automatic switch procedure, so that the coordinator user session information is cleared 460 from the client device 120 and/or the server application 133 (backend system), while the subject user information (username and password) are kept on the client device 120.

In an embodiment, the proprietary application 124 may go to default state (login view, for example) when the coordinator logs out in step 450. The subject user's username and password can be used to automatically pre-fill the login input fields (username and password) or used in direct network login request to the server application 133 of the backend system.

Order of logout of coordinator 450 and reset procedure 460 to reset coordinator session data may vary and they can be performed in any order or simultaneously.

Keeping the subject user's username and password in the system can be done in practice by storing them on the client device 120 persistent storage 320 and/or kept in application 330 or device memory. Using these credentials automatic login procedure 470 can be done by creating a login request to the server 130 and the server application 133.

The proprietary application 124 may go to default state (login view, for example) after coordinator logout step 450. The kept subject user's username and password may be used to pre-fill the login input fields (username and password) for login step 475 or used in direct network login request 470 to the backend system.

In an embodiment, the subject user can manually press a login button with the pre-filled username and password input fields as in step 475 if completely automated end-to-end login process 470 is not desirable.

In step 480, the subject user is logged in, i.e. authenticated, and continue using the client device 120 and the proprietary application 124 for the clinical trial until logging out the subject user as in step 490.

In an embodiment, steps 410-440 may correspond to manual interactions between the coordinator and the proprietary application 124, steps 450-470 to automatic interactions by the service system and/or the proprietary application 124, and steps 475-490 to manual interactions between the subject user and the proprietary application 124.

In an embodiment, an alternative solution of operations is where the coordinator user steps 410-470 are automated by the system.

In such embodiment, the coordinator user provides the client device 120 to be available for use in a designated area. A subject user may then take the client device 120 into use and credentials, such as username and password are fetched from the proprietary application 133 of the backend system. This can be done prior or while the subject user takes the client device 120 into use or while the subject user is already using the client device 120.

The subject user can manually activate the automatic login procedure (e.g. by pressing a button with text: “start”) or it can be initiated automatically as the client device 120 is taken into use.

Optionally, the subject user can manually press the login button with pre-filled username and password input fields if completely automated end-to-end login process is not desirable.

Stored credentials of the subject user comprising username and password can be used to pre-fill the login input fields (username and password) or used in direct network login request to the server application of the backend system and no manual interaction is required from the subject user. Then, the subject user is logged in, i.e. authenticated, and the subject user may continue using the client device 120 and the proprietary application 124.

In an alternative version described above, the coordinator user could also verify after logout of each subject user that the client device 120 is still operational and optionally reset the client device 120 for new use. Here it would be possible also that the subject user credentials are created beforehand for the next subject user.

FIG. 5 shows a flow chart of a process according to an example embodiment of the invention.

A computer implemented method starts in step 510. The computer implemented method is suitable for transceiving clinical trial related information between a client device operable by a plurality of users and a server apparatus, wherein the client device and the server apparatus are configured to communicate via a data network. A proprietary application of the client device may be a client application of a clinical trial service whose server application is running on the server apparatus, wherein a coordinator user profile associated with coordinator credentials and a subject user profile associated with subject credentials are maintained by the server application at the server apparatus.

In step 520, the coordinator credentials are received via a user interface by the proprietary application, the coordinator credentials are accepted in response to determining the coordinator credentials being authorized credentials, and the coordinator user is logged in by providing coordinator level access to the proprietary application.

In step 530, coordinator input data is received by the proprietary application configured to trigger user change for the client device.

In step 540, a request is generated and sent by the proprietary application in response to the coordinator input data to the server application indicating the triggered user change.

In step 550, subject credentials are received by the proprietary application from the server application, wherein the subject credentials being associated with the subject user profile generated by the server application.

In step 560, the coordinator user is logged out by disconnecting coordinator level access to the proprietary application and resetting the coordinator credentials and session data within the client device.

In step 570, the subject credentials are stored by the proprietary application for automatic first logging in of the subject user.

In step 580, the method ends.
